How deep in debt we are?

All Polonius wouldnt have gotten very far in America today. He's the Shakespeare character in Hamlet who warned, neither a borrower, nor a lender be.

Modern society, as we know all too well, is overrun with both borrowers and lenders. But just how big is the typical family's debt? How fast is it growing? How does your mortgage compare to the Joneses next door? And how might consumer debt -- your debt -- affect the U.S. economy?

We decided to look at the most recent numbers and take a snapshot of household debt in the United States, circa 2004. What emerges is a picture that's both familiar and unsettling. Yes, consumer debt -- encompassing credit cards, mortgages, student loans and more -- is growing like a well-fed St. Bernard puppy. No, there's no sign that the growth will slow. Yes, some economists worry about the ill effects, but no, not many of them are sounding urgent alarms.

It's hard not to be worried when confronted with numbers such as these:

About 43% of American families spend more than they earn each year.

Average households carry some $8,000 in credit card debt.

Personal bankruptcies have doubled in the past decade.

It's not clear exactly where the debt trend will take U.S. consumers or the U.S. economy. But it is clear that both are sailing in uncharted waters.

Consumers owe nearly $2 trillion

American consumers owed a grand total of $1.9773 trillion in October 2003, according to the latest statistics on consumer credit from the Federal Reserve. Thats about $18,654 per household, a figure that doesnt include mortgage debt. The number is up more than 41% from the $1.3999 trillion consumers owed in 1998.he majority of consumer borrowing, about 63%, is represented by so-called "non-revolving" debt such as automobile loans. But "revolving" credit, which most typically involves credit cards, is an increasingly significant part of the equation. Revolving debt currently totals $735.3 billion; that's about 31% higher than it was only five years ago. The figure has more than doubled in a decade.

Among the key drivers of debt expansion in recent years:

Unusually low interest rates.

The rising popularity of Internet shopping, in which credit cards are the currency of choice.

The hot housing market, which has encouraged buyers to stretch for new homes.

The aggressive extension of credit to consumers with weak credit scores.

Credit for consumers with fair or poor credit ratings typically comes with higher fees and interest rates, says Lydia Sermons-Ward, spokeswoman for the National Foundation for Credit Counselors. And while that access to capital helps some disenfranchised consumers, the availability of risk-based credit has also greatly increased the amount of debt per household and could lead to more financial problems for families, Sermons-Ward says.

There is a tendency for consumers to take advantage of credit offers without really thinking through the consequences of overspending, she says.

Just one word: plastics

The average amount of credit card debt in households with more than one card is now more than $8,000, according to CardWeb.com. Thats 167% more than the $3,000 average for households in 1990.The average American has 2.7 bank credit cards, 3.8 retail credit cards and 1.1 debit cards, for a total of 7.6 cards per cardholder, CardWeb.com said. About 18% of all personal consumption expenditures in the country are made on bank credit cards. Add in retail cards and debit cards and the figure rises to 24%.

The most unsettling aspect of all these credit card transactions is that many Americans dont see their income as a spending cap. About 43% of U.S. families spend more than they earn, according to a Federal Reserve study. And on average, Americans spend $1.22 for every dollar they earn, according to Myvesta.org.

Are high debt levels threatening to dampen consumer spending, which accounts for about two-thirds of the U.S. economy? Bank One Chief Economist Anthony Chan says decidedly yes. He flatly predicts that consumers will spend less in 2004 because of the amount they are borrowing.

Household liability as a percentage of disposable income is at its highest level ever in the United States, Chan said. Yes, its too high. Next year consumer spending will probably lag growth in real GDP by a percentage point or even more.

To make up for the effect of the high debt burden, job growth will have to soar, he says. We need to see employment picking up and wages picking up before we see the consumer being able to avoid the impact of the high level of consumer credit.

The mortgage rush
Mortgage debt is the next major piece of the debt picture. In fact, the amount owed on mortgages dwarfs the amount owed on credit cards or other loans. The average principal amount owed on a mortgage is $69,227. Nearly 14 million homeowners, about 19% of all homeowners in the country, owe more than $100,000.

Because of historically low interest rates -- often below 6% for 30-year loans -- many homeowners have been overborrowing, says Mark Zandi, chief economist at Economy.com. Debt loads were already onerous, and they have been borrowing very aggressively in recent years, he says.
